The reason why i don't want laptop, because if screen broke or is bad - i need to buy new device. This is not 1) Cost-effective 2) Comfortable
With NUC i can buy display i like. Any size i want. And it all will be portable - easy to move or work while travelling.
Sometimes i am OK without battery.
Mostly i use UPS instead of battery which is same effective as battery.
I believe small desktops are still bigger and is not boxed well enough. Also lacks thunderbolt connectors all desktop i can found.
I believe it won't overheat by default, but i really want 4.5 GHz CPU overclock or more.
